Savepower

Savepower is a simple and effective daemon for the cpufreq userspace governor. It is designed for workstations and servers, where all actions have to be done at the fastest speed, and after some idle time, maximum power savings are desired. It increases clock frequency to the maximum immediately on busy CPUs, and reduces the clock to the lowest frequency after a period of inactivity. The polling frequency is 1 second and can easily be shortened.
